Manufacturers of different
brands of mouthwashes often claim that their brand is better, kills
more bacteria, and prevents bad breath for a longer
time.

Different brands of mouthwashes
also have different price ranges. Are you getting a better and more
effective product when you buy a more expensive brand?

Like any other consumer product,
mouthwash can be tested for effectiveness in removing
bacteria and killing bacteria.

Project
description:
In this project you will perform experiments to compare different
mouthwashes for their ability to kill germs. The
experiments in this project require some bacteria growth
experience.
